Notes on the protective conductor resistance test 1

Observe the instructions in the safety rules for installation and repair
(ARTD-002.731.17 ...).

The protective conductor resistance of 0.2 ohms must not be exceeded.

Initial measurement

Perform the protective conductor test after completion of all work.

The measurement must be made according to DIN VDE 0751, Part 1 (see ARTD Part 2).
In this case the protective conductor resistance in the normal operating condition to all
conductive touchable parts of the system must be measured.

Make sure that control cables or data cables between the components of the system do
not imitate any protective conductor connection.

During the measurement, move the power cable and additional connection cables with
integrated protective conductor section by section to detect cable breaks.

The protective conductor resistance must not exceed 0.2 Ohms.

The values must be recorded as initial measurements in the report ’Protective conductor
resistance / report’ stating the measuring points.

Notes on device leakage current measurement 1

Observe the instructions in the safety rules for installation and repair (ARTD-002.731.17).

WAR NING

Electrical voltage!
Non-compliance can lead to severe injuries and even death.

The device leakage current measurement may be
performed on systems of protection class I only after the
protective conductor test has been passed.

Initial measurement

Perform the device leakage current measurement after completion of all work.

Perform the measurement according to DIN VDE 0751, Part 1 (see ARTD-002.731.17...),
and record the determined value as the first measured value.

Measurement of the device leakage current according to the differential current method
(measuring arrangement according to Fig. 2) must be given preference, since no danger
for the person performing the measurement and other persons arises during the measure­ment.
However, please note the minimum resolution of the leakage current measuring instru­ment and any additional manufacturer's data restricting the use of the measuring instru­ment.

WAR NING

Electrical voltage!
Non-compliance can lead to severe injuries and even death.
No housing parts of the system may be touched during the mea­surement in the direct measurement of the device leakage current
(measuring arrangement according to Fig. 3).
Third-person access to the system must be prevented.

The system must be switched on during the measurement. Measuring instruments with
automated measuring sequences must therefore be set to manual measurement.

Enter the highest value as first measured value in the report ’Device leakage current /
report’.

This value must not exceed the permissible leakage current values according to
DIN VDE 0751-1:2001-10, Table F.1, line "Device leakage current for devices according to
remarks 1 and 3", of 2.5 mA.

Measure and record the current line voltage. If the measured line voltage deviates from
the nominal voltage, then correct the measured value to the value corresponding to a
measurement at the nominal value of the line voltage. Document this in addition.

Document the measuring procedure (differential measurement or direct measurement)
and the measuring instrument used (designation and serial number).

Repeat measurement

When service or repair work is performed on the primary power supply circuit (e.g. repairs
to the power-on circuit or replacement of the line filter), the device leakage current test
must be repeated.

The same measuring conditions as in the first measurement apply.

Siemens AG RXB8-115.034.02 Page 7 of 8 POLYMOBIL III
Medical Solutions Rev. 03 04.05 CS PS 24

1 - 8 Requirements

Record and assess the highest value determined in the repeat measurement in the exist­ing report ’Device leakage current / report’.

This value must not exceed the permissible leakage current values according to
DIN VDE 0751-1:2001-10, Table F.1, line "Device leakage current for devices according to
remarks 1 and 3", of 2.5 mA.

Measure and record the current line voltage. If the measured line voltage deviates from
the nominal voltage, then correct the measured value to the value corresponding to a
measurement at the nominal value of the line voltage. Document this in addition.

Document the measuring procedure (differential measurement or direct measurement)
and the measuring instrument used (designation and serial number).

NOTE

Evaluate the results by comparing the first measured value to the
corresponding values documented during preceding mainte­nance procedures or safety checks.
A sudden or unexpected increase of the measured values may
indicate that a fault has occurred in the primary circuit of the
power supply (damaged insulation, damage caused by humidity,
defective interference suppressor, etc.) - even if the limit value of

2.5 mA is not exceeded.

5 - 2 Final work steps

• The system must be switched on during the measurement. Measuring instruments with

automated measuring sequences must therefore be set to manual measurement.

• Enter the highest value as first measured value in the report ’Device leakage current /

report’ (chapter 7 of these instructions).

• This value must not exceed the permissible leakage current values of 2.5 mA according

to DIN VDE 0751-1:2001-10, Table F.1, line "Device leakage current for devices
according to remarks 1 and 3".

• Transfer the current line voltage from the ’Start-up report’ into the report ’Device leakage

current / report’. If the current line voltage deviates from the nominal voltage, then correct
the measured value to the value corresponding to a measurement at the nominal value
of the line voltage. Document this in addition.

• Document the measuring procedure (differential measurement or direct measurement)

and the measuring instrument used (designation and serial number).

Reports 5

• Separate the completed 'Start-up report' (chapter 6 of these instructions) from these

instructions and file it in the system folder, "Certificates" register.

• Separate the completed reports 'Protective conductor resistance / report' and

’Device leakage current / report’ (chapter 7 of these instructions) from these instructions
and file them in the system folder , "Certificates" register.

• Complete the 'Installation Protocol' located on the system and send it (per fax) to the

address stated in the protocol.

Last work steps 5

• Wind the power connection cable onto the cable holder on the back of the control

console.

• Lock the support arm in the traveling position (Fig. 1) and check the forced locking of the

support arm.
